COTTON-SEED DELINTER.

SPECIFICATION forming part of Letters Patent No. 555,040, dated February 18, 1896.

Application filed January 2, 1896. Serial No. 574,002. (No model.)

To all whom it may concern:

Be it known that I, JAMES J. FAULKNER, a citizen of the United States, residing at Mem-' phis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Cotton-Seed Delinters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines for treating cotton-seed, and particularly to improvements in that class thereof known as delinters; and it consists in the improved block-holding device Whose construction Will be hereinafter described, and particularly pointed out in the claims.

The object of my invention is to provide an improved form of fastening for securing an abrading-block upon the revolving surface of a cotton-seed delinter.

Heretofore prominent among the difficulties which have been experienced in the practical operation of that class of delinters to which the cotton-seed delinter which forms the subject-matter of my present application belongs-namely, a delinter having a revoluble delinting-cylinder, with abrading-blocks removably secured to its periphery, and a casing thereforhas been that of providing means for preventing the blocks being unseated or torn from their fastenings by the intense strain to which they are are subjected in the operation of the machine. This difficulty has up to the present time been insurmountable, and is all the more important because the loosening of a single abradingblock is apt to result in the tearing of the e11- tire machine to pieces before the same can be stopped and the injury -repaired.

In accomplishing the object of my invention I bevel the ends of the abrading-blocks which I provide for the revolving surface of a cotton-seed delinter, the beveled port-ion being at the base of the block, and make use of two-faced holding devices,each face being formed with a dovetailed groove or recess to enable it to receive the beveled end of the block. These recesses are opposite in direction, and an abrading-block is held between the recesses formed in adjacent holding devices; and I bevel one side of the block near its base and form the delinting-cylinder of a series of disks, each disk being only wide enough to receive a single block and being formed on one side with a peripheral beveled flange or projecting rim, against which the beveled face of the block may be pressed and held. Cement or plaster may then be used to hold the blocks perfectly rigid in their position upon the disks.

In order to still further facilitate the passage of the seed through the machine, I sometimes form on one side of the block at the base 6 a projecting flange and bevel the outer face of the flange, instead of beveling the side of the block itself. In this. case I insert the blocks between the edges of the block-holders and force them in until the beveled-faced 7 flange firmly contacts with the peripheral proj ecting rim. In this manner a space is formed between adjacent blocks, which provides a free channel for the passage of the seed through the machine, while the beveling of 7 the face of the block or of the flange, as the case may be, enables the block to be forced against the projecting rim and thus be securely seated and at the same time minimize the amount of inactive surfacet'. a, that of the flange upon the delinting-cylinder.

My invention is fully illustrated in the drawings which accompany and form a part of this application, in which the same reference-letters refer to the same or corresponding parts.

Figure 1 is a vertical section showing the location of the parts. Fig. 2 is a detail perspective view of the central shaft with two disks or cylinder-sections thereon. Fig. 3 is a detail perspective view of one of the disks. Fig. 4 is a detail view of one of the abradingblocks. Fig. 5 is a central transverse section of an abrading-block, showing the depth of the central groove. Fig.6 is a detail view of an abrading-block provided with a side flange, a section or portion of one of the disks being shown in connection therewith. Fig. 7 is a detail view of an abrading-block formed with beveled corners, a correspondingly-formed holding device being shown in connection therewith.

Referring to the drawings, A represents the machine-frame. In this frame are formed suitable bearings for the central power-shaft 1), upon which is mounted a delinting-cylinder l5, and by the frame is supported the casing C. The scouring or abrading surfaces of the machine consist of the abrading-blocks 1), secured to the surface of the delinting-cylinder, and the emery-linedinner surface of the delinting-cylinder casin g.

Seed is fed into the machine through a feedpipe E, formed at the head end of the machine, and is discharged at the opposite or tail end of the machine through any suitable and wellknown discharge-pipe. The conveying of seed through the machine is effected in part by the natural gravitation of the seed when subjected to the influence of a revolving abrading-surface and in part by the spiral formation of the abrading-blocks upon that portion of the delintingcylinder nearest the feed-opening, which will hereinafter be described in detail. The dirt separated from the seed by the action of the machine is removed from the inclosure in which the abrading action is taking place through suitable perforations F, formed in the bottom of the delinting-cylinder casing. The lint which is scoured from the seed by the action of the machine is withdrawn from the inclosure by the joint action. of the lint-removal saws G, which project through suitably-spaced openings in the delbiting-cylinder casing, and of an exhaust-air current generated by the exhaust-fan ll stationed in the air-llume I. It is in this air-flu me that the lint-removal saws G are journaled, and such saws are so placed that their peripheries will project a short distance into the delinting-cylinder casing, so that they will seize and remove the long fibers of lint as rapidly as they are separated from the seed under treatment. A dolling-brush J is used to keep the lint-removal saws clean and to prevent the gathering of lint thereupon.

My present invention resides in the means used to secure the abrading-blocks in position on the surface of the delinting-cylinder. As the form of the abrading-blocks, however, has been modified with special reference to the character of the hold i n g devices employed, I will describe such blocks in detail.

The abrading-block which I now use is formed, as shown in the drawings, with inclined sides (Z, an upper surface (l, which slopes upward from the front to the rear of the block, and a groove (Z extending longitudinally of the block on its upper surface, the bottom of such groove being parallel to the base of the block. The inclination of the sides of the block results in a rounded active abrading-surface, which is the most favorable form for effecting the desired scouring of the surface of the seed under treatment, while yet prex enting injury to such seed. The slope of the upper surface of the block is very sharp at the front end of the block, until the height of the block nearly equals that which the block possesses at its rear end, the slope thereafter being very gradual. This formation enables the intensity of the seonring action of the abrading'surface to increase as the block passes over the seed under treatment, while the almost perpendicular formation of the rear end of the block allows the seed which has just been subjected to the abrading action to spring outward and change its position, so that a new surface may be presented to the abrading action of the next block. The groove which is formed upon the upper surface of the block effects the double purpose of enabling a larger extent of abrading-surface to be utilized than would otherwise be available and of affording a channel through which the seed may pass.

It must be remembered that in this type of machine the distance between the delintingcylinder and the inner surface of the cash: g does not usually exceed five-eighths of an inch, so that some outlet or chaunelas, in this case, the groox c d n1ust be provided for the seed under treatment.

The ends of the block are beveled, as shown at d, in order to enable the blocks to be held by the double-faced holding devices K, secured to the surface of the delintirig-cylinder, and on one side of the blocks, at their base, there is formed a longitudinal dmvnwardly and inwardly sloping beveled face (1", which enables the blocks to be fitted snugly against the peripheral projecting rim L, formed upon each of the disks or cylindeasections L, and thus to be securely seated. I sometimes, in order to form additional channels through which the seed under treatment may pass, form on one side of the block at its base a projecting flange (l and bevel the outer face (1 of the flange. Either construction may be used.

The abrading-blocks thus described are secured to the surface of the delinting-cylinder by the two-faced holding devices K, which are formed, as shown, on both sides with dovetailed recesses 75, and are secured by screws or otherwise to the surface of the debuting-cylinder. The delinting-cylinder itself is made up of a number of disks or cylindersections L, each such section being of the width of a single block and having a number of holding devices secured to its periphery. On one side of such disks there is formed a projecting rim L, which is beveled so as to enable the beveled face of the abradingblocks to fit snugly thereagainst. In this manner 1 am enabled to firmly seat the blocks upon the cylindrical surface, and especially to remove the lateral strain to which they are ordinarily subjected by reason of their violent action. A suitable cement or plaster, preferably plaster-of-paris, is used after the blocks are in position to assist in holding the blocks firmly in position and preventing any movement thereof.

Instead of using the ordinary form of holding devices, as shown in Figs. 1, 2, and 3, I sometimes bevel the corners of the abradingblock, as shown at al and form the holding devices with corresponding-extended corners thus enabling such corners to grasp and hold the beveled corners of the abradingblock. This fastening is somewhat more secure than the ordinary form.

As indicated in Fig. 2, the abrading-blocks at the head end of the machine are set on a slight spiral, so as to facilitate the feeding or conveying of the seed through the machine. This means I have found to be quite effectual without resorting to any additional element of construction.

When a number of disks are used upon a central shaft, it is necessary to provide means for balancing the cylinder formed thereby in order to obtain the proper movement of the same. This I accomplish in my present construction by forming the feather b upon the shaft, and providing on the inner surface of the openings through which the shaft passes through the various disks or cylinder-sections a number of recesses Z, through any one of which the feather b of the central shaft may pass. By a suitable choice of the recesses through which the feather passes through the various disks the cylinder may be perfectly balanced and a proper revolution thereof secured.

I do not herein claim the use of a moving lint-rem oving device, stationed in an air-flume in free communication with the inclosure in which the delinting operation is taking place and formed to permit free passage of air therethrough, as this is claimed in a separate application for Letters Patent filed by me May 20, 1895, Serial No. 549,980.

I do not herein claim the novel features of the abrading-block which is shown and described, except so far as they assist in enabling the block to be held in place upon the periphery of the revolving abrading-surface; nor do I claim the construction by means of which I am enabled to balance the disks forming the cy1inder-surface upon the central shaft, as these matters are claimed in a separate application for Letters Patent filed by me January 28, 1896, Serial No. 577,166; but
